    •Do not supply signals from color cameras and black-and-white cameras simultaneously to the camera input
    connectors since this may disturb the synchronization on the monitor screen or generate noise.
    •During playback, turn the Quasi-V insertion to ON or OFF with the FWD ADV button. This enables the appearance
    of the pictures of other cameras to be reduced.

    Playback Procedure
    Before operating the unit, check that the internal/external timer recording displays (INT/EXT) have been cleared from
    the display. (If INT or EXT is displayed, use the TIMER MODE switch to clear it.)
    rPress the PLAY button.
    PLAY
    qSwitch on the power to the unit and TV monitor.
    wInsert the recorded cassette tape into the unit.
    eSelect the time mode.
    TIME MODE
    Notes on operation
    1. Bear in mind the following points when playing back parts of a tape recorded in a time lapse (L18 to 240 hour)
    mode.
    •When the tape is played back in the same mode, noise resembling dropouts will appear on the screen: this is not
    indicative of malfunctioning.
    •The picture may oscillate in the vertical direction: this is not indicative of malfunctioning.
    •When a tape is played back in the same time mode, the picture may shake slightly sideways: this is not indicative
    of malfunctioning.
    •Turn Quasi-V insertion ON (
    ) or OFF () with the FWD ADV button. Dancing can be minimized when a tape is
    played back in a time lapse (L18 to 240 hour) mode. Moreover, playing back a tape in a system featuring a frame
    switcher enables the appearance of the pictures of other cameras to be reduced.
    2. Bear in mind the following points when playing back parts of a tape recorded in a VHS mode (6 hours).
    •When a tape is played back in a time lapse mode, slight noise may appear at the top and bottom of the screen:
    this is not indicative of malfunctioning.
    3. When noise has occurred during still-picture playback, press the FWD ADV button to play it out. (It may not always
    be possible to play out the noise.)
    4. Bear in mind that if the power cable is disconnected and then re-connected or if the power has been restored after
    it has failed when the tape was played with EXT indicated on the display by the TIMER MODE button, the unit will
    automatically be set from playback to the recording mode.
    5. When the PAUSE/STILL button is pressed during playback, the unit is set to the pause mode, and a still picture
    PLAY button. If the unit is kept in the pause mode for more than 5 minutes, it will be set to the stop mode.
    6. If the horizontal AFC on the TV monitor is too long or when a video camera with random interlace scanning has
    been used, the top area of the TV monitor may be distorted: this is not indicative of malfunctioning.
    7. A tape recorded in the 2-hour mode on a different deck can be played back in the 2-hour mode. However, it cannot
    be played back in time lapse (L18 to 240 hour) mode.
    •“6H” appears when a tape is played back which was recorded for 6 hours using another VTR.
    8. Tapes recorded on this machine cannot be played back other VHS video recorder as they are not compatible.
    9. When the power cord has come out of the socket or a power failure has occurred during fast forwarding or
    rewinding, no operations will be acknowledged for about 30 seconds after the power has been restored: this is to
    protect the tape.
    Tracking
    When noise such as that shown below appears on the
    playback image in the 6-hour time mode, press the
    tracking (+ or –) button to minimize the noise.
              
              
    TRACKING /
    V-LOCK
    •For the tracking default setting, press the “+” and “–”
    buttons together (in the 6-hour time mode only).
    •In the L18 or L24 hour mode, press the “+” or “–”
    button to adjust the tracking.
    Vertical Hold Adjustment
    If the image shakes slightly in the vertical direction
    during still-picture playback, press the V-LOCK buttons
    (–, +) to reduce the dancing.

    1. Outline of RS-232C interface
    This interface is for enabling the basic functions of the VTR to be operated using a personal computer.
    The D-SUB 9P connector is used to connect the VTR with the personal computer.

    As soon as the receive buffer becomes full, receive buffer overflow is returned, and subsequent commands are 
    canceled.
    The ACK or NAK response must commence within 20ms.
    When a new command has been received during the processing of an non-interruptible command, the receive 
    verification code is returned within 20ms, after which the applicable ERROR code is returned, and the 
    processing of the previous command is resumed.
    When it takes time for execution to be completed, it is to be possible for the next command to be processed (in 
    principle, after the ACK response) without waiting for the completion of the said execution. (This applies only to 
    commands whose processing can be interrupted.)
    When a command which does not entail a transfer of the deck mode is received, the message of having 
    completed the received command is returned regardless of the deck mode. ■Explanatory description
